Common Errors

What follows are examples of the most common errors that newcomers to
JavaScript make. They are presented to you so you will be aware of these kinds
of errors and can avoid them as you write your code. They aren't presented
in any sort of technical order and aren't a complete list by far, but if
you can learn to identify these, your JavaScript projects will have a much
better chance of working the first time.

Typos and Spellos!

Most of the errors you'll encounter when writing JavaScript (if you
follow the examples laid down here) will probably fall into these categories.
Typos occur when you accidentally hit the wrong key or combination of keys while
typing.
